Here's more or less what I used for testing.

You can run it without an argument - it will then try PURE_JAVA
backup, or the first argument specifies what kind of backup it should try.
Change the variables in the code to match your connection parameters.

java file content:

import java.sql.*;
import org.firebirdsql.management.*;


class JBIRD2PureJavaError {
Connection conn;
//set these to your bidding
String dbuser="SYSDBA",dbpass="masterkey",
role=null,charset="UNICODE_FSS";
String databasePath="pathToYourDB";
static String backup_type="PURE_JAVA";


public static void main(String args[]) {
if(args.length>0) backup_type=args[0];
new JBIRD2PureJavaError();
}

JBIRD2PureJavaError() {
conn=null;

try{ Class.forName("org.firebirdsql.jdbc.FBDriver").newInstance();
String connstring="jdbc:firebirdsql:embedded:"+databasePath;
if(charset!=null||role!=null) connstring+="?";
connstring+=charset!=null?"lc_ctype="+charset+(role!=null?"&":""):"";
connstring+=role!=null?"sql_role_name="+role:"";
conn = DriverManager.getConnection(connstring,dbuser,dbpass);
} catch(Exception e) {
e.printStackTrace(System.out);
}
System.out.println("Backing up with backup type "+backup_type+":");
try{
FBBackupManager fbBackup=new FBBackupManager(backup_type);
fbBackup.setUser(dbuser);
fbBackup.setPassword(dbpass);
//fbBackup.setHost("localhost");
fbBackup.setDatabase(databasePath);
fbBackup.setBackupPath(databasePath+".fbk");
fbBackup.setLogger(System.out);
fbBackup.setVerbose(true);
fbBackup.backupDatabase();
} catch(Exception e) {e.printStackTrace(System.out);}

try{conn.close();}catch(Exception e) {e.printStackTrace(System.out);}
}
}
